NEW! RBPS II

Rechargeable Battery Power Supply II
(RBPS) for Stroboflash II, III, IV

Bring your 20, 30, 40 even 50 year old Stroboflash in to the 21st century. Replace those really EXPENSIVE old Eveready 489's with a "state of the art" 12v/24v to 450v switch mode power supply (SMPS). That's right! I just LOVE Stroboflash, the finest portable photographic strobe light ever designed. This is a brand new state of the art rechargeable power supply that will fit right in the Stroboflash II or Stroboflash IV case. RBPS plugs right on the existing battery connection pins of the Stroboflash pack. No wiring required. Just add batteries and start shooting.

Uses a widely available 12v rechargeable Nickel Metal Hydride (NiMH) batteries. Recycle time using a Stroboflash IV on FULL power is 4 seconds!! 1/4 power is < 2 seconds. Flashes per charge are in excess of 200!!  Up to 1000 discharge / recharge cycles. 81 cents per 1000 flashes!

Designed and Made in USA!

In an effort to save you money and keep things simple we do not sell the batteries and chargers. These types of batteries are widely available on the internet and from hobby shops. You can pretty much use any battery as long as it can output at least 4aH at 12volts and will fit in the Stroboflash case. We suggest NiMh batteries but NiCd (a little cheaper) or Lithium (expensive!) will work just fine.

 Batteries and chargers- please purchase from links below:

Batteries:
Need Qty. 1  RB-HC10R2T-MT5000 Robot / RC car batteries

Battery Chargers:
Need Qty 1  CHUN-123

OR

12v Battery and Smart Charger Combo:

CH-UN180C37 

 

Alternate Battery sources:

Batteries and chargers are available at most hobby shops. They are used for robots and remote controlled cars. Any 12v NiCd or NiMh battery pack will work (make sure it fits in to your case!). Must be minimum 2500 mAh. 5000mAh or larger is best. 12v lead acid, lawn mower or car battery is great too but probably wont fit in the Stroboflash case.
